As nice as it would be for Microsoft to kind of run those IDE's and toolsets, I think it would be bad for the market altogether, we can't have just one company running every developer offering out there, competition is good. I hope someone else buys them out though, just to see how that ends up.
This, in so many ways. I'd be considered a Microsoft schill, and even I don't like that idea. Microsoft needs companies like Apple, Google, and JetBrains to keep them from getting complacent.
